What it means
This rule checks the invoice currency code (BT-5), the cbc:DocumentCurrencyCode element, and flags it if it has a listID attribute. The value is a three-letter ISO 4217 code such as EUR. In UBL, listID would name the code list, but EN 16931 fixes the list, so the attribute is not used.
Why it matters
EN 16931 uses the invoice currency code without a listID attribute. This check concerns the extra attribute, not the currency code value.
How to fix it
Remove listID from cbc:DocumentCurrencyCode and keep the currency code unchanged. If your software adds the attribute, ask its supplier to correct the export, then check the new file again.
Once the file is corrected, check it again for free: Validate an invoice against EN 16931
